/r 'y v Applicatonjflled February 20, 1926. Serial No. 89,544. i

- The principal objects of the present invention are to, snub or check aslack rope in starting to hoist a bucket or load from a position of restas at the `bottom of a lift; .tol diminish the strain on the rope whenstarting to hoist load; to avoid injury to the rope :when slack cable istaken 'up suddenlv; to `provide a simple, eflicient, and reliable re Asilient connection between vthe cable and load; to avoid bending thecablev when the load travels around bends:A and to provide a simpletake-up for adjustingrk the length of the cable.

Other objects of the invention will appear '15 Vfrom the followingdescription vat the end ments to be presently described and finallyclaimed. v

In the following description reference will be made to the accompanyingdrawing formw ing part hereof and in Which- Figure 1 is an end viewillustrating` features of the invention, and

Fig. 2 is'a side vieu7 ofl Fig. 1. f

In the drawing 1 is` a spool Wheel around which the end part2 of therope or cable is Wrapped substantially 1% turnsor more. 3 are clipsv forsecuringr the end 4 of the rope to the reach 5 thereof. 6 is a shaft onwhich the spool AWheel 1 is mounted. 7 are angle. structures in Whichthe shaft 6 is carried and in respect to which the spool Wheel or drumis revoluble and Which are vadapted, for attachment to the skip bucketVor counter- Weight, or morefaccuratelvto the'portion thereof indicatedat 8. The parts 7 may be vregarded as one form'offrame.4

If, for example, the bucket, counterweight `orthe like is restingontheground or is otherwise supported at the bottom of the lift, and if thecable is slack, then in starting to hoist theV load the turnable drum inco-' operation with the oppositely directed turns of the cable around itsnubs or checks the cable. diminishing' the strain on it and'avoids ing`injury to it, and this is true perhaps to a less entent even if thecable is notvdistinctly slack. When the load traverses curves; or Whenthe line of draft'is inclined to the `line of travel, as shown in Fig. 1by dotted lines, ythe cable or rope is not bent but the drum or To takeup the rope or Wheel is turned. shorten the cable the clips 3 may beremoved and the end 4C of the cablemoved further up the `reach thereof,the 'turning of the drum facilitates this movement, andthen theclips`can be reapplied`- It Will be obvious to those skilledvin'the i i artyto which the invention relates that modifications may be made inldetails of con struction and arrangement and in matters of mere formWithout departing from' the spirit of the invention which is not limitedto such matters or `otherwise than as the prior art and the appendedclaims may require.

l claim 1. Means for fastening hoistingr rope to skip buckets and thelike which comprise a circular spool Wheel around which the endv `partof the rope 1s Wrapped at least sub-v stantially '1% turns,devices forsecuring the end of the rope to the reach thereof, and aframe in whichthe spool Wheel isturnably mounted and which is adapted for `attach`ment to the skip bucket'and the like. i

2. Means for fastening' hoisting rope to skip buckets and the like whichcomprise a circular spool Wheel 'around which the end part of the ropeis Wrapped at least sub1k stantially 1% turns, clips for securing'theend of the rope to the reach, thereof, a shaft i on Which'the 'spoolWheel is mounted, and

angle structures in which the shaft is carried and in respect to `whichthe spool Wheel is c revoluble and which are adapted for attachment tothe skip bucket or the like.
